What you likely need

You'd get the most out of Festival events that put you in front of institutional LPs and family offices actively backing emerging micro-VC managers, where your Carta top-decile 2022 vintage data can do the heavy lifting. Roundtables and dinners with YC alumni operators and B2B SaaS founders would sharpen your deal flow edge and reinforce your Operator Stack thesis. You'd also benefit from small gatherings with other operator-turned-investors building public positioning in fintech and SMB payments, where a co-authored thesis or panel appearance could accelerate LP inbound.
